NVENTOR JOHN O. BUBMAN, F LOWELL, MASSACHUSETTS.

To all whom it ma concern;

Be it known t at I, JOHN O. BURMAN,

' a citizen of the United States, residing at Lowell, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Burn-* ers, of which the following is a specification.

My present invention has relation to certain new and useful improvements in gas burners and as its primary object it contemplates the provision of a novel device of this character that is especially designed to be used in connection with conventional forms of grates and bed plates therefor in order to expedite the starting or the. reviving of the fire.

Another object of my invention is to provide a burner of this nature that may be cast in a single piece and afterward cored out at suitable points to form the necessary chambers and burner openings and which, by reason of its particular construction, may be easily and quickly attached or removed from the respective bed plate.

Another object is to provide an efiicient means for shieldin the 'jet openings from the deteriorating e ects of the heat and from becoming clogged by the ashes or other solid matter falling from the grate.

Anotherobject is to provide forspreading the jets of fluid fuel after it emerges from the jet openings, so that the spreader cooperates with the row of jet openings and forms a sheet of fluid' thereby assuring the igniting of all of the ets whenone of them is ignited.

A further object of my invention is to provide a device of the type in question that is extremely simple in construction, strong and durable, and highly-practical from both the standpoint of the manufacturer and the standpoint of the user; and which, it is be-' lieved, may be manufactured at a comparatively low cost. v Y

Various other ob ects and advantages Wlll become apparent during the continuance" of the following description.

These objects are accompllshed by such means as areshown in their preferred form in the accompanying drawings, described in the following'specification and then more specifically pointed out in the appended,

claim.

like characters designate like parts throughout the several views Figure 1 is a view. in plan of a grate and bed plate of substantially the conventional form showing my invention in conjunction therewith Fig. 2 is a view in longitudinal section of the burner showing more clearly the manner of attaching the-same to the bed plate of the grate;

Fig. 3' is a crom sectional view taken on line 33 of Fig. 2. a

In the drawings, I have shown a .bed plate 10 that is of substantially the conventional form and which is designed to support a grate 11 of the usual'construction. At certain points the base plate 10is provided with suitable securing ears 12 and 13 respec-.

tively (see Fig. 1), to which'the burner may be attached in the manner hereinafter described.

In reducing my invention to practice, I first provide a base 14 that is preferably constructed of a cast metal and which carries a depending enlargement 15 (see Fig. 2) which constitutes to a great extentthe body portion of the burner.- Although not limiting myself in any way to the specific manner by which the base 14 and the enlargement 15 may be connected, it is pointed out that these two elements may be cast in one piece, if it is so desired.

The enlarg'ementlfi is cored out longi tudinally as at16 (See Fig. 2) to form a S itable mixin and fuel dispensing chamher while it is urther provided with lateral fuel may find egress. Theseyopenings 17 -may be arranged in any desired and well known manner so as to project the flame through the .grate .11 into contact with the fuel lying thereon; but, by means of a horizontal extension or spreaderll' I prefer to direct the flame from the jets 17 horizontally under the grate 11 and allow the draft of the stove to draw the flame throuh the grate into the solid fuel. The sprea er 17 also constitutes a shield for the jet openings,

and also a reinforcement for the mixing chamber, to support the latter and to receive the brunt of the deteriorating effects of the heat. v

In. connecting the burner to the said plate 10, the extended portion 14 of the base 1* ofthe burner is arranged to lie on the securing ear 13, as shown in Figs. 1 and 2 whereby a fastening member as designated at 18 may be passed therethrough, to attain a secure connection while a second fastening member 19 may be passed through the other securing car 12 into the enlargement 15, as shown 1n Fig. 2. By this arrangement, it will be noted that the burner may be securely positioned in lace and thus held against accidental dis odgment' during the operation of the grate.

A nipple 20 may beconnected with the enlargement 15 as at 21 to project exteriorly of the stove and may be cut away as at 22 to provide a suitable air ngress opening.

A noz'zle23 has its egress opening in'the air inlet 22. A sliding cover sleeve 24 is arranged tobe movable on the nipple 20 whereby it may be utilized to regulate the admittance of air through the cut away por tion 22, or to completely close the same in the event that such is required by the operator. A usual gas pipe 24' may be connected with the nipple 2O in-the ordinary manner and egress thereinto controlled through the instrumentality of a suitable valve such as designated by the numeral 25.

In the operation of the burner, thesleeve 24 is first arranged on the nipple in a desired manner soas to regulate theingress of air through the cut away portion 22 after which the gas may be turned on by W y Of the valve 25, and the mixture of air and gas takes place in the mixing chamber 16 and may be lighted upon egress through the openings 17. As before stated the ingress of air through the cut away portion, 22 may be adequately regulated so. that the proper mixture of air and gas may be attamed.

From the foregoing it is apparent that I have provided an improved burner that may be quickly and easily attached to or removed from conventional forms of bed plates and cast in a single piece, whereby it may be manufactured at a minimum cost. In view of the fact that the advantages and novel features of my invention will be readily apparent from the foregoing, it is believed that further detail description is deemed unnecessary. a

In reducing my invention to practice, I find that the form referred to herein as the most practical and preferred embodiment -is the most efiicient, but realizing that certain conditions will necessarily vary in concurrence With the adoption of my device, I desire to emphasize the fact that various minor changes in the details of construction and in the proportion of parts may be resorted to when required without sacrificing any of the advantages of my invention as defined in the appended claim.

Having thus fully described my invention, What I claim as newand desire to secure by Letters Patent is In combination, a grate rest of substantially U-shape having, inwardly extending ears at the extremities of the spaced members, and a fuel burner bridging the space between the said members and forming coilnecting means therefor, said burner comprising a lower hollow portion, which at one end underlies one of the said ears and is attached thereto, and an upper plate portion which is extended at oneend and overlies the remaining ear and is attached thereto, and which projects inwardly to overhang the said hollow portion, the latter having a plurality of openings in its inner wall ad acent the overhanging portion of the plate.

In testimony whereof I afiix my signature in presence of two witnesses.
